Do CompileBPFAsmFromxxx methods compile BPF assembler to BPF instructions or CPU ones?
A. These methods compile the BPF assembler program in BPF instructions set. The program that is created at that can be compiled in the CPU instructions set at the level of PSSDK library driver, if either HNAdapter.UseFastUserFilter property is set to TRUE, or after HNUserFilter.CompileToFastBPF method call if the filter is used at the application level.
